PRESS FQR PACKING BRAN, 80o.

SPECIFICATION forming part of Letters Patent No. 357,814, dated February 15, 1887.

Application filed March 15, 1886. Serial No. 195,244. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES H. BROWNE, of Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Presses for Packing Bran, 850., of which the following is a specification.

This invention relates to an improvement in that class of presses which are composed of a jointed pressing-case into which the material is compressed from the receiving case or chamber by a follower which is actuated by a screw.

The object of my invention is to construct a press of this character which is suitable for pressing or packing bran and other similar material, and which is easily manipulated and actuated with a comparatively small expenditure of power.

My invention cnsists,to that end,of theimprovements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure l is a sectional front elevation of my improved press. Fig. 2 isaseetional side elevation of the same. Fig. 3 is a top plan view of the same. Fig. 4 is a horizontal section in line or m, Fig. 1. Fig. 5 is a vertical section of the pressing-ease on an enlarged scale. Fig. 6 is a vertical section of the upper portion of the pressing-case in line yy, Fig. 5,011 an enlarged scale. 7 Fig. 7 is a horizontal section in line 2 2, Fig. 5. .Fig. 8

is atop plan view of the bottom frame of thepressing-ease. Fig. 9 is a fragmentary sectionalside elevation of the upper receivingcase and crosshead. Fig. 10 is a vertical section of the upper cross-head and receivingcase. Fig. 11 shows one of the spring-catches reversed.

Like letters of reference refer to like parts in the several figures.

A represents the stationary main frame of the machine; B, the jointed pressingcase,

which can be removed from the machine and opened for withdrawing the pressed block of bran or other material.

(3 and D represent, respectively, the upper and lower receiving-cases, from which the material is compressed into the case B by the followers E and F.

it represents the horizontal driving shaft provided with the necessary tight and loose pulleys a for turning the shaft in either direc tion, or stopping it, as may be desired. The

shaft ais journaled in suitable bearings secured to the top portion of the main frame.

I) is a horizontal counter-shaft, which re ceives motion from the drivingshaft a. by gear wheels b If, and which transmits motion to a horizontal countershaft, c, bygear'wheels cc. The shaft 0 is arranged in line with the driv' ingshaft a, and carries a pinion, c, which meshes with two gear'wheels, c. The latter are secured to horizontal counter-shafts d, arranged on opposite sides of the counter-shaft 0, and carry bevel gear-wheels d.

ff represent two vertical screw-shafts arranged on opposite sides of the receiving-cases O and D, and journaled in bearings f at the top of the frame A,and in steps f at the bottom of said frame. The screw-shafts f f are provided at their upper ends with horizontal bevel-wheels g, which are driven by the bevelwheels d. The screwshafts f workin threaded openings or nuts in the followers E and F, and each shaft is provided with a right-and-left screw, so that the followers are moved by the screwshafts in opposite directions. The screwshafts are preferably supported neartheir middle in bearings f secured to the front posts of the frame A.

The receiving-cases O and D and the pressing-case B are preferably made square in cross-section. The upper receiving-case, O, is rigidly secured to the frame A, so as to be stationary, while the lower receivingcase, D, and the pressing-case -B are made vertically movable, so that they can be lowered from theupper case, 0, when the operation of pressing is completed. The side walls of the receiving-cases O and D are provided with vertical slots h h, through which the arms h" h of the followers E and F move. These slots are closed by movable covers H H, titted against the outer sides of the cases 0 and D and sliding in horizontal ways it" If. The sliding covers H H are pressed against the followers by springs h M, and the contiguous sides of the followerarms h h and covers H H are madeinclined, so that the follower-arms will press these covers backward and out of the way as the followers move toward the pressing-case B,while the springs h ld-will return the covers to their former positions as the followers move away from the pressing-case.

I represents ,the feed-spout, through which the bran or other material to be pressed is delivered into the upper end of the upper receiving-case, C. The upper follower, E, is provided with a suitable opening, 1', through which the material passes into the case 0.

E represents the removable follower-board, which is applied to theunder side of the follower E. This board is removed and applied through an opening, 1', formed in thefront of the case and provided with a sliding cover,i

F represents a similar removable board apand lined with coarse wire-cloth k'fiwhieh permits of the escape of the air from the bran and prevents the sack from slipping in the pressing-case during the operation of compressing the bran.

Lrepresents spring bolts or catches attached to the upper and lower ends of two of the side walls of the pressing-case B, on opposite sides thereof, for the purpose of locking the follower-boards against the block or package of bran in the case B when the pressing is completed. The ends of the bolts L are beveled to permit the follower-boards E F to press the bolts back as the boards enter the pressingcase B. hen the pressing is completed, the follower-boards have passed the bolts L and the latter are projected by their springs, as represented in Fig. 6. The pressing mechanism'is so timed that the follower-boards are forced into the case B a short distance beyond the catches L, so that when the pressure is removed, the reaction of the compressed material will take place in the case B and force the follower-boards back against the catches, thereby preventing the compressed material from expanding after it is removed from the case B, which would result in a change of form and size in the compressed block or package.

The follower-boards E F are covered with sacking when they are introduced into the receiving-cases G and D. After the material is pressed the bolts L are turned by means of the hand-levers l,with which they are provided, so that there beveled or inclined faces are reversed, which permits the ready removal of the follower-boards.

The bottom frame, J, of the pressing-case B is provided with rollers m, which are adapted to run on rails m when the case B is lowered, thereby affording ready means for moving the case B to and from the receiving-case O.

The lower receiving-case, D, has a limited vertical movement in the frame A, and is provided for that purpose with vertical slots n,

through which pass headed studs 1%, which are secured to the frame A. c

The lower end of the case D is provided with a bridge-tree, 0, which rests upon the front end of a lever, 0. Thelatter is pivoted to the lower portion of the frame A, and is provided at its rear end with a weight,o ,'which counterbalances the weight of the cases B and D and connecting parts, which rest upon the lever 0'.

0 is a vertical shifting-rod, which is attached to the rear end of the lever 0', and pro- 7 vided with a nose, ofiwhich bears against the stop 0 on the frame Awhen the cases B and D are elevated.

P is an arm which projects rearwardly from the lower follo\ver,F. This arm strikes against the nose 0 of the shiftingrod 0 when the press ing is completed, thereby releasing the shift ing-rod and permitting the cases B and D with the compressed package to descend until the rollers of the case B rest upon the rails m. The shifting-rod 0 is provided with a projection or treadle, 0, for depressing the rod and elevating the cases B and D.

Q is a spring or elastic buffer, which is secured to the bridge-tree 0, and which strikes against thelower portion of the frame A when the case D descends, thereby arresting the downward movement of the case gradually.

B. represents a plate arranged upon the lower follower, F, and supporting the lower followerboard, F. The'lower case, D, may be provided with an opening, 1, protected bya slide, '2", through which opening the board F may be inserted and removed. The plate R is provided with a downwardly-extending stem, 8, which is guided in an opening in the follower F, and rests upon the front end of a lever, S.

The latter is pivoted to the lower end of a vertical rod, 23, which is connected with its upper end to a scale-beam, T.

a is a vertical rod attached withits lower end to the rear end of the lever S, and provided near its upper end with a nose, u,which engages tunder a fixed stop, a". The upper end of the rod to is provided witha treadle, a Upon depressing the rod to the plate It is lifted from thefollower F, whereby the plate and the board F resting thereon are caused to support the material in the cases B, O, and D. In this position of the parts'the weight of the material is indicated by the scale-beam T, and when the proper quantity has been introduced into these cases the supply is shut off. Upon disengaging the rod u from the stop a the plate R descends and rests upon the follower F, thereby rendering the weighing contrivance inoperative.

When the cases B and D are elevated, as represented in Figs. 1 and 2, the press is ready to receive the material. The material passes into the cases D, B, and G from the spout I, and when the desired quantity has been received the supply is'shut off and the upper follower-board is introduced into the upper case, 0. The screw-shafts f are now set in motion, whereby the followers E and F are moved toward the pressing-case B, forcing the ma terial from both receiving-cases O and D into pressing is completed, the actuating mechana, which is moved by an arm, '0, on the upper follower, E. By reversing the motion of the screw-shafts the pressure is removed from the followers, and then the pressing-caseB is permitted to rest upon the rails. The shiftingrod is at the same time disengaged from the stop 0 thereby permitting the lower case, D, and the pressing-case B to descend. The follower-boards E and F are locked against the upper and lower sides of the package of compressed material in the case B by the springcatches L. Thecase B is now run out on the rails m, opened, and the package removed.

A sack or bag is again placed in the case B,

' the latter returned under the upper case, 0,

and the lowercase, D, and case B are elevated by depressing the rod 0 The followers are returned to their former position by reversing the motion of the actuating mechanism and the operation is repeated. In this manner a powerful pressure is applied to the material from both ends of the chambers in which the material is contained, and as no bending of the screw-shafts is liable to occur these shafts and the connecting parts can be made comparatively light without sacrificing safety. The power required for effecting the compression is comparatively small, and the machine is operated with great speed and convenience.

I claim as my invention 1. In a press, the combination, with two receiving-cases, of an intermediate movable pressing-case capable of being placed in communication with both receiving cases, and adapted to be removed therefrom for discharg- 7 ing the compressed package, and followers 1 moving in the receiving-cases toward and from the intermediate pressingcase, substantially as set forth.
